一项关于老龄小鼠的实验研究结果证实,生殖系统对哺乳动物的寿命起着决定性作用。来自于美国加利福尼亚大学的James Kaili教授及其同事将2个月龄的小鼠卵巢移植到老龄小鼠体内,受试老龄小鼠的卵巢均在出生后的3周内被摘除。移植的结果是部分老龄小鼠的寿命得以延长。Kaili教授对此解释说,该结果等同于使一位年满50岁的妇女活到其通常的期望寿命92岁,而不是80岁。 An experimental study on aging mice confirmed that the reproductive system plays a decisive role in mammalian life. Professor James Kaili from the University of California, Los Angeles, and his colleagues transplanted ovariectomized 2-month-old mice into aged mice. All the ovaries of the aged mice were removed within 3 weeks after birth. As a result of transplantation, the life span of some old mice is prolonged. Professor Kaili explained that the result was equivalent to living a woman over the age of 50 to her usual life expectancy of 92 instead of 80.
